text: Background The United States has many international agreements that require treaty partners to provide certain information to IRS, which can help prevent the use of foreign bank accounts to facilitate tax evasion. FATCA goes much further, requiring FFIs to report more detailed information to IRS about their U.S. customers annually. These provisions are important developments in efforts to combat tax evasion by U.S. persons holding investments in offshore accounts. FATCA generally requires certain taxpayers to report foreign financial accounts and other specified foreign financial assets whose aggregate value exceeds specified thresholds to IRS on Form 8938. These taxpayers must report these assets and income generated from such assets to IRS with their tax return on Form 8938. These thresholds vary by filing status—such as single or married filing jointly—and by domestic or foreign residency. FATCA also promotes third-party reporting of foreign financial assets by requiring a withholding agent to withhold 30 percent on certain payments to an FFI unless the FFI or the jurisdiction in which the FFI is located has entered into an agreement with the United States to report certain account information of their U.S. customers. Under such an agreement, participating FFIs report detailed information to IRS annually about accounts held by their U.S. customers using an IRS Form 8966, FATCA Report (Form 8966). According to IRS, FATCA improves visibility into taxable income from foreign sources, and enhances the agency’s ability to identify and pursue taxpayer noncompliance. For example, FATCA allows IRS to compare information reported by FFIs on Forms 8966 to information reported by U.S. persons on Forms 8938. According to IRS, this comparison can be used to ensure taxpayers and FFIs are properly reporting foreign financial assets and income from international investments. This type of comparison is a common IRS enforcement technique. For example, IRS can directly compare information it receives from financial institutions’ IRS Form 1099-INT, Interest Income, against a tax return to determine if the taxpayer reported income generated from interest earned. To facilitate FATCA implementation for FFIs operating in jurisdictions with laws that would prohibit FFIs from complying with the terms of the FFI agreement, Treasury developed two alternative intergovernmental agreements (IGA)—Model 1 and Model 2—to facilitate the effective and efficient implementation of FATCA by removing partner jurisdictions’ legal impediments to comply with FATCA reporting requirements, and reducing burdens on FFIs located in partner jurisdictions. FFIs from countries with Model 1 IGAs report information on U.S. persons’ accounts to their respective host country tax authorities (HCTAs). The HCTAs, in turn, compile the information from FFIs and transmit it to IRS. In contrast, FFIs from countries with Model 2 IGAs, or countries treated as not having an IGA in effect, directly report information on U.S. persons’ accounts to IRS. Separate from the FATCA requirements, regulations implementing the Bank Secrecy Act of 1970 (BSA) also impose a separate self-reporting requirement for foreign accounts. Specifically, certain taxpayers and residents are required to file an FBAR with FinCEN annually if they have financial interest or signature or other authority over one or more foreign financial accounts with a total of more than $10,000, regardless of whether they reside within or outside the United States. Federal, state, and local law enforcement agencies can use information from these reports to combat financial crimes, including terrorist financing and tax evasion. Appendix IV provides a comparison of Form 8938 and FBAR reporting requirements. Figure 1 depicts the flow of foreign financial account information from U.S. persons and FFIs to IRS and FinCEN through the FATCA and FBAR reporting processes. FATCA Data Limitations and Lack of a Comprehensive Strategy Have Hampered IRS Efforts to Increase Compliance Incomplete and Inaccurate Reporting of Taxpayer Identification Numbers by FFIs Has Limited IRS’s Efforts to Match Account Information for Compliance Purposes As part of the FATCA reporting requirements, IRS collects information on financial accounts through forms and reports submitted by both taxpayers and FFIs. As part of this effort, IRS requires taxpayers to identify their TINs on Forms 8938 they submit. IRS also requires participating FFIs to report the TINs of each account holder who is a specified U.S. person on Forms 8966. IRS intends to use reported TINs to link Form 8938 data filed by taxpayers to Form 8966 data filed by the FFIs to ensure that taxpayers and FFIs are properly reporting foreign financial assets. However, IRS often could not link account information collected from FFIs to the account’s owner because of incorrect or missing TINs. In July 2018, the Treasury Inspector General for Tax Administration (TIGTA) found that almost half of new Forms 8966 filed by FFIs did not include a TIN or included an invalid TIN. A consulting firm working with FFIs to implement FATCA reporting requirements told us that FFIs encountered significant challenges obtaining accurate TINs from U.S. persons as part of the self-certification process. For instance, FFIs encountered situations where U.S. persons provided incomplete or inaccurate TINs—such as Social Security Numbers (SSN) with less than nine digits—on forms used to self-certify their status as U.S. persons. FFIs also encountered situations where U.S. persons may not have obtained TINs or were unwilling to provide them to FFIs. Additionally, banking associations told us that it has taken time, effort, and expense for FFIs to report TINs, as they had to upgrade computer systems to collect and record TINs from U.S. customers. Finally, Treasury told us that jurisdictions that have an IGA with the United States but no legal requirement to collect TINs are not in compliance with the requirements of the IGA. Treasury and IRS determined that some FFIs reporting from countries with Model 1 IGAs needed additional time to implement procedures to obtain and report required U.S. TINs for preexisting accounts that are U.S. reportable accounts. Consequently, IRS provided a transition period, through the end of 2019, for compliance with the TIN requirements for FFIs under Model 1 IGAs. Specifically, in September 2017, IRS issued a notice modifying procedures for FFIs reporting from countries with Model 1 IGAs to become compliant with TIN reporting requirements for preexisting accounts. For calendar years 2017-2019, IRS will not determine that certain FFIs in countries with Model 1 IGAs are significantly noncompliant with their obligations under the IGA solely as a result of a failure to report U.S. TINs associated with the FFI’s U.S. reportable accounts, providing they (1) obtain and report the date of birth of each account holder and controlling person whose TIN is not reported, (2) make annual requests for missing TINs from each account holder, and (3) search electronically searchable data maintained by such FFIs for missing required U.S. TINs before reporting information that relates to calendar year 2017 to a partner jurisdiction. As a result, even without any further extensions, calendar year 2020 is the earliest IRS will be enforcing requirements for FFIs from countries with Model 1 IGAs to provide accurate and complete information on U.S. account holders’ TINs to IRS. Without valid TINs on Forms 8966 submitted by FFIs, according to IRS officials, IRS faces significant hurdles in matching accounts reported by FFIs to those reported by individual tax filers on their Forms 8938. As a result, IRS must rely on information such as names, dates of birth, and addresses that the filers and/or FFIs may not consistently report. Without data that can be reliably matched between Forms 8938 and 8966, IRS’s ability to identify taxpayers not reporting accurate or complete information on specified foreign financial assets is hindered, interfering with its ability to enforce compliance with FATCA reporting requirements, and ensure taxpayers are paying taxes on income generated from such assets. In July 2018, TIGTA reported that IRS lacked success in matching FFI and individual taxpayer data because reports FFIs filed did not include or included invalid TINs. This, in turn, affected IRS’s ability to identify and enforce requirements for individual taxpayers. TIGTA recommended, among other things, that IRS initiate compliance efforts to address and correct missing or invalid TINs on Form 8966 filings from FFIs from countries with Model 2 IGAs or without any IGAs with the United States. IRS management said it disagreed with this recommendation because a system to ensure validation of every TIN upon submission of a Form 8966 would be cost prohibitive. However, IRS management said that IRS would address invalid TINs as they are uncovered on other compliance efforts, such as initiating development of a data product to automate risk assessments across the FATCA filing population. IRS also said it continues efforts to systematically match Form 8966 and Form 8938 data to identify nonfilers and underreporting related to U.S. holders of foreign accounts. However, IRS management told us they are waiting until they have a full set of data, including TINs, before doing analysis to develop a compliance strategy. According to TIGTA, IRS management believed that having the FFI’s Global Intermediary Identification Number (GIIN) on Form 8938, which is filed by the taxpayer, would help with matching records. However, Form 8938 instructions identify that the field is optional for taxpayers to complete. TIGTA recommended that to reduce taxpayer burden in obtaining GIINs from FFIs, IRS add guidance to Form 8938 instructions to inform taxpayers on how to use the FFI List Search and Download Tool on the IRS’s website to obtain an FFI’s GIIN. IRS agreed with this recommendation. However, even if an individual taxpayer provided GIINs, IRS may continue to have difficulty matching accounts with U.S. taxpayers if the TIN and name of the account holder reported on the Form 8966 do not match the TIN and name of the taxpayer on the Form 8938. IRS officials said they are aware of these difficulties and have attempted to match Forms 8938 and 8966 based on other criteria such as dates of birth. In its response to our draft report, IRS said that all financial institutions and foreign tax authorities that file required account information receive a notification listing administrative and other minor errors contained in their reporting. According to IRS, its Large Business and International division follows up with foreign tax authorities regarding these errors to ensure the tax authorities are working with financial institutions to correct these errors in compliance with the countries’ IGAs. IRS added it has initiated a campaign addressing FFIs that do not meet their compliance responsibilities with respect to account opening requirements. Additionally, IRS drafted a risk acceptance form and tool addressing risks in implementing FATCA compliance and business process capabilities. This risk assessment focused on the limitations IRS faces due to budget constraints, but did not address the specific risks it faces from not receiving complete and valid TINs on U.S. account holders. We previously reported that risk management could help stakeholders make decisions about assessing risk, allocating resources, and taking actions under conditions of uncertainty. Key management practices for risk management we identified from our prior work include identifying, analyzing, and prioritizing risks; developing a mitigation plan to address identified risks; implementing the plan; and monitoring, reporting, and controlling risks. Without developing a risk mitigation plan to address risks IRS faces from not receiving complete and valid TINs moving forward, IRS may lose opportunities to adjust its compliance programs to better identify U.S. persons who are not fully reporting specified foreign financial assets as required under FATCA. IRS Databases Lack Consistent and Complete FATCA and Taxpayer Data Useful for Compliance Enforcement and Research Several IRS databases store data collected from individuals’ electronic and paper filings of Form 8938 and/or elements of parent individual tax returns to which the Form 8938 is attached—the filer’s country of residence and filing status—used to determine specified reporting thresholds for Form 8938 filers. Additionally, data from these databases and other sources are transferred downstream to IRS’s Compliance Data Warehouse (CDW)—a database used for research and analytical purposes. We extracted data from copies of Individual Return Transaction File (IRTF) and Modernized Tax Return Database (MTRDB) data copied into CDW to obtain information reported on Forms 8938 and relevant information from parent tax returns, such as filing status and filers’ country of residence. We found that IRTF and MTRDB had inconsistent and incomplete data. For example, neither database had consistent and complete information on foreign financial account and other asset information submitted by Form 8938 filers. While IRS officials told us that IRTF is the authoritative source for filers of Form 8938, it does not store account and other asset information submitted on Forms 8938. Additionally, IRS officials said MTRDB is not designed to store information submitted on paper filings of Forms 8938 and parent tax returns. Officials from IRS’s Research, Applied Analytics and Statistics (RAAS) division also noted that CDW did not have reliable information from Form 8938 paper filings. Because of the lack of foreign financial asset information from such filings, we could not report complete information on assets reported by Form 8938 filers. Further, IRS does not provide instructions to CDW users on how to extract appropriate data from CDW—such as data copied from IRTF and MTRDB—leading to confusion on which databases to use for extracting Form 8938 and relevant parent tax return data. For example, five distinct tables within CDW are required to identify the TIN, parent form, filing status, country of residence, and amount of foreign assets accurately. Without clear explanations of how data in each of these tables relate to each other and to the underlying filings, errors could be introduced into CDW users’ analyses of foreign asset information. Standards for Internal Control in the Federal Government notes that management should use quality information to achieve the entity’s objectives. One attribute of this principle includes processing data into quality information that is appropriate, current, complete, accurate, accessible, and provided on a timely basis. Additionally, the Internal Revenue Manual states that IRS needs to measure taxpayer compliance so that customer-focused programs and services can be enhanced or developed so that compliance information and tools can be improved. According to IRS officials, IRS researchers have been taking additional steps to obtain and review Form 8938 and parent tax return data stored in the Integrated Production Model (IPM) database. They said IPM is the only database that contains complete data from individuals’ electronic and paper filings of Forms 8938 and relevant elements of parent tax returns. IRS officials said that RAAS has been working with IRS’s information technology (IT) division to obtain read-only access to IPM, and import Forms 8938 and 8966 data from IPM into CDW for analysis. However, as of February 2019, this effort has been delayed due to budget constraints. In its response to our draft report, IRS said that obtaining read-only access would require a new technical process and plans to continue working with IT on the feasibility and timeframe for enabling this access. Enabling access to consistent and complete Form 8938 and parent tax return data for compliance staff and researchers from RAAS and other IRS business units would help IRS strengthen its efforts to enforce compliance with FATCA reporting requirements and conduct research to bolster enforcement efforts. However, such efforts may be hampered until IRS can ensure readily available access to such data. IRS Stopped Pursuing a Comprehensive Plan to Leverage FATCA Data to Improve Taxpayer Compliance We previously recommended that IRS develop a broad strategy, including a timeline and performance measures, for how IRS intends to use FATCA information to improve tax compliance. IRS agreed with this recommendation and developed a strategy for FATCA in July 2013. IRS updated the strategy in 2016 by creating the FATCA Compliance Roadmap as a comprehensive plan to articulate IRS’s priorities to facilitate compliance with FATCA reporting requirements. The roadmap also provided an overview of compliance activities used solely for enforcing FATCA reporting requirements or enhancing existing compliance efforts. However, in July 2018, TIGTA reported that IRS had not updated the FATCA Compliance Roadmap since 2016, and had taken limited or no action on a majority of the planned activities outlined in it. We also found that IRS had not yet evaluated the effects of FATCA, including the effects on voluntary tax compliance. IRS documentation states that only 7 of 31 capabilities outlined in the FATCA Compliance Roadmap were delivered due to funding constraints. As of October 2018, IRS has stopped using the FATCA Compliance Roadmap and has not developed a revised comprehensive plan to manage efforts to leverage FATCA data to improve taxpayer compliance. According to IRS officials, IRS moved away from updating broad strategy documents, such as the FATCA Compliance Roadmap, to focus on individual compliance campaigns. These include a campaign to match individual tax filers to the reports from FFIs, and another campaign to identify FFIs with FATCA reporting requirements who are not meeting all of their obligations. According to what IRS told us, with the passage of time and as FATCA is becoming more integrated into agency operations, it has moved from updating the broad strategy documents focused on FATCA to working on compliance campaigns that incorporate FATCA into overall tax administration. Additionally, IRS and outside researchers plan to study the role of enforcement in driving overall patterns in reporting offshore assets and income generated from such assets. Though IRS maintains that FATCA is more integrated into its operations, TIGTA’s 2018 report concluded that IRS was still unprepared to enforce compliance with FATCA in part because it took limited or no action on the majority of planned activities outlined in the FATCA Compliance Roadmap. Documenting a framework for using FATCA reporting requirements to improve taxpayer compliance and measure their effect is consistent with three steps we found leading public sector organizations take to increase the accountability of their initiatives: (1) define clear missions and desired outcomes; (2) measure performance to gauge progress; and (3) use performance information as a basis for decision-making. We also previously reported that it is important for IRS to use a documented framework that defines a clear strategy, timeline, and plans for assessment. Having such a framework in place can help IRS better allocate resources and avoid unnecessary costs resulting from not having the necessary or appropriate data available to execute its objectives. In light of the challenges IRS faces to collect, manage, and use FATCA data to improve compliance in a resource-constrained environment, employing a comprehensive plan would help IRS maximize the use of collected data and better leverage individual campaigns to increase taxpayer compliance. Without such a plan, IRS’s ability to collect and leverage data collected under FATCA for compliance enforcement and other purposes is constrained. Analysis of FBAR and FATCA Data Provide Insights, Including the Possibility that Tens of Thousands of Forms 8938 May Have Been Filed Unnecessarily More than 900,000 Individual FBAR Filers Reported about $1.5 Trillion or More in Foreign Accounts in Both Calendar Years 2015 and 2016 We could not report on total values of foreign financial assets on Forms 8938 in tax years 2015 and 2016. However, we could provide a range of total maximum account values reported on FBARs during the same period. Specifically, we determined that more than 900,000 individuals filed FBARs in calendar years 2015 and 2016, and declared total maximum values of accounts ranging from about $1.5 trillion to more than $2 trillion each year. A little more than one in five—or about 21.7 percent—of the approximately 404,800 Forms 8938 filed with IRS in tax year 2016 were done so from U.S. persons living abroad, with the other 78.3 percent living in the United States. Table 1 shows that a higher proportion of Form 8938 filings from U.S. persons living abroad for tax year 2016 were filed on paper (43.3 percent) than Form 8938 filings from U.S. persons living in the United States during the same period (14.7 percent). We extracted these data from IRTF, which IRS officials said is the authoritative source for filers of Form 8938. However, we could not report complete information on foreign financial assets reported by Form 8938 filers because such data are incomplete; as noted above, IRS databases we used to extract Form 8938 data—IRTF and MTRDB—do not include asset information reported on paper filings of Forms 8938. Tens of Thousands of Forms 8938 May Have Been Filed Unnecessarily in Tax Year 2016 Of the approximately 404,800 Forms 8938 filed by individuals for tax year 2016—the most recent data available—we could access information on residency of filers and reported foreign financial assets from about 277,600 Forms 8938 that did not indicate that foreign financial assets and values were declared on other forms besides the Form 8938. Of the subset of these Forms 8938, more than one quarter—or about 73,500— reported foreign financial assets in amounts that indicate the Form 8938 may have been filed unnecessarily, since they reported specified foreign financial assets with aggregate values at or below reporting thresholds as of the last day of the tax year. Based on available Form 8938 data from tax year 2016, table 2 shows that about 61,900 filings from U.S. persons living in the United States and about 11,600 filings from U.S. persons living abroad during the same tax year reported specified foreign financial assets with aggregate values at or below end of tax year thresholds. These totals likely understate the total number of Forms 8938 that U.S. persons may have filed unnecessarily in tax year 2016; due to data limitations, these totals exclude Forms 8938 without asset information stored in IRS’s databases, including most Forms 8938 filed on paper and Forms 8938 where filers identified that they declared foreign financial assets on other forms besides the Form 8938. There is no clear explanation as to why some U.S. persons may have filed Forms 8938 unnecessarily. However, we identified a number of potential reasons from focus groups and other interviews with stakeholder groups. In focus groups we conducted, participants expressed confusion about IRS’s instructions for completing the Form 8938 and information provided on IRS’s website. In the instructions for completing Form 8938, IRS described the specific types of foreign financial assets that are to be reported on Form 8938, and the asset value thresholds that must be met for required reporting, depending on the location of residence and filing status of the taxpayer. IRS also posted responses to frequently asked questions on meeting FATCA reporting requirements on its website, and established a separate page on its website comparing foreign financial assets that must be reported on Form 8938 and/or FBAR. Nonetheless, focus group participants reported confusion on whether and how to report investment and retirement accounts and compulsory savings plans managed by their country of residence. In a meeting we convened with an organization representing tax attorneys, they told us taxpayers are unsure about what account values to report on the Form 8938. Tax practitioners participating in another focus group added that they filed Forms 8938 regardless of the aggregate value of the assets because it was too cumbersome for them to identify whether the assets exceeded reporting thresholds as of the end of the year or at any time during the year. IRS officials also cited a number of possible reasons why U.S. persons may be filing Forms 8938 unnecessarily. For example, it may be easier for U.S. persons to report all specified foreign financial assets they hold on the Form 8938, rather than determine whether the value of such assets met applicable thresholds. IRS officials also said that U.S. persons might complete a Form 8938 for reasons besides meeting tax-filing requirements, such as providing evidence of assets for a loan application. IRS’s Taxpayer Bill of Rights states that taxpayers are entitled to clear explanations of the laws and IRS procedures in all tax forms, instructions, publications, notices, and correspondence. Furthermore, one of IRS’s strategic goals is to empower taxpayers by making it easier for them to understand and meet their filing, reporting, and payment obligations. IRS officials said they hosted sessions for tax practitioners at IRS Nationwide Tax Forums to address FATCA reporting requirements. However, they said IRS has not taken direct steps to identify or implement actions to further clarify instructions and related guidance on IRS’s website for completing Form 8938, such as information on which foreign financial assets to report, how to calculate asset values, and determine whether such values exceed required reporting thresholds. Additionally, IRS officials said they have not conducted additional outreach to educate taxpayers on required reporting thresholds under FATCA, or notify Form 8938 filers of instances where aggregate values of specified foreign financial assets reported on Forms 8938 were below reporting thresholds. IRS officials said they have not made efforts to determine whether there is a pattern of unnecessary Form 8938 filings that they could address. Rather, they said they believed resources should be devoted to FATCA implementation in general. However, as shown above, we have identified many tens of thousands of instances where U.S. persons may have filed Forms 8938 unnecessarily. Without assessing factors contributing to unnecessary Form 8938 reporting—and identifying or implementing actions to further clarify and educate taxpayers on FATCA reporting requirements—IRS is missing opportunities to help taxpayers understand their filing and reporting obligations and minimize their compliance burdens while properly meeting their tax obligations. Additionally, IRS may be missing opportunities to reduce costs in processing forms that taxpayers did not need to file. Different Laws Established Overlapping Foreign Financial Asset Reporting Requirements and Compounded Taxpayer Compliance Burden Because of overlapping statutory reporting requirements, IRS and FinCEN—both bureaus within Treasury—collect duplicative foreign financial asset data using two different forms (Form 8938 and FBAR). Our evaluation and management guide for fragmentation, overlap, and duplication states that overlap occurs when multiple agencies or programs have similar goals, engage in similar activities or strategies to achieve them, or target similar beneficiaries. Table 3 shows that individuals required to report foreign financial assets on Form 8938, in many cases, also must meet FBAR reporting requirements. For example, specified individuals with foreign financial accounts exceeding $50,000 in aggregate value on the last day of the tax year must file both Form 8938 and FBAR if such values exceed the minimum Form 8938 thresholds; these thresholds depend on the filing status and address of specified individuals. Table 3 also shows that, in many cases, specified interests in foreign financial assets as defined in Form 8938 instructions are the same as the financial interest in such assets under FBAR. Further, as noted in table 3, the overlapping requirements lead to IRS and FinCEN collecting the same information on certain types of foreign financial assets. For example, both Form 8938 and FBAR collect information on foreign financial accounts for which a person has signature authority and a financial interest in the account. Form 8938 and FBAR also both collect duplicative information on several other types of foreign financial assets, such as foreign mutual funds and accounts at a foreign financial institution that include foreign stock or securities. Overlapping reporting requirements result in most Form 8938 filers also filing an FBAR during the same reporting year. Table 4 shows that close to 75 percent of Form 8938 filers in tax years 2015 and 2016 percent also filed an FBAR for the same year using the same TIN. Overlapping requirements to file both Form 8938 and FBAR increases the compliance burden on U.S. persons and adds complexity that can create confusion, potentially resulting in inaccurate or unnecessary reporting. Focus group participants in all five countries included in our study affirmed that U.S. persons experienced confusion and frustration with having to report duplicative foreign financial asset information on both forms. Focus group participants and others we interviewed also noted that U.S. persons incurred additional financial costs to complete and file both Form 8938 and FBAR. For instance, one tax practitioner in Canada said the charge was about $190 to report four-to-five accounts on an FBAR in addition to charging about $540 for basic tax return packages. An accounting firm based in Japan typically charged between $300 and $800 to complete a Form 8938 and between $150 and $500 to complete an FBAR, depending on the number of accounts reported on the forms. Proposed revisions to regulations implementing BSA proposed by FinCEN may also increase the number of duplicative foreign financial accounts reported on Form 8938 and FBAR. Currently, U.S. persons must report detailed information on all foreign financial accounts on Form 8938 if the value of such accounts and other specified foreign financial assets reaches applicable reporting thresholds. In contrast, U.S. persons are generally exempted from reporting detailed account information on FBARs if they report having signature or other authority over 25 or more foreign financial accounts. FinCEN’s proposed revisions to BSA regulations would eliminate the exemption, requiring U.S. persons to report detailed information on all foreign financial accounts in which he or she has a financial interest if the value of such accounts exceed FBAR’s $10,000 reporting threshold. FinCEN estimated that it will receive account information for the first time on about 5.4 million foreign financial accounts if it finalizes the proposed revisions. In turn, these revisions may lead to increased filings of duplicative asset data on both Form 8938 and FBAR, as U.S. persons may have to report detailed information on all foreign financial accounts using both forms. U.S. persons also face exposure to two different penalty regimes for any failures in accurately and completely reporting foreign financial asset information to two bureaus within Treasury—IRS and FinCEN. Officials from one organization representing U.S. persons living abroad said penalties due to failure to report certain accounts on one or both forms can be significant, even if little or no taxes are owed on those accounts. The duplicative reporting of foreign financial asset data on two different forms also creates additional costs to the government to process and store the same or similar information twice, and enforce reporting compliance with both requirements. In 2012, we recommended that Treasury direct the Office of Tax Policy, IRS, and FinCEN to determine whether the benefits of implementing a less duplicative reporting process exceed the costs and, if so, implement that process. Treasury did not implement our recommendation. While we continue to believe that the agencies should have considered whether less duplicative reporting could have been implemented, we do recognize that FATCA and FBAR were enacted under two different statutes to serve different purposes. As mentioned above, according to IRS, FATCA improves visibility into taxable income from foreign sources and enhances the agency’s ability to identify and pursue taxpayer noncompliance. In contrast, the information reported on the FBAR is collected to identify money laundering and other financial crimes; law enforcement agencies can use BSA information—including information collected from FBARs— to aid regulatory and criminal investigations. Additionally, data collected from Form 8938 and FBAR are used in different systems for use by different bureaus within Treasury. Fully addressing issues stemming from overlapping reporting requirements and the resulting collection of duplicative information—while at the same time ensuring that such information can be used for tax compliance and law enforcement purposes—can only be done by modifying the statutes governing the requirements. Further, IRS and FinCEN have varying degrees of access to foreign financial asset information collected from Form 8938 and FBAR to enforce tax compliance and financial crime laws. FATCA was enacted, in part, to improve visibility into taxable income from foreign sources. However, information provided on Forms 8938 is taxpayer return information protected by section 6103 of the Internal Revenue Code (IRC), which generally prohibits IRS from disclosing information provided on Forms 8938. IRS can share return information with other government agencies and others when it is allowed by statute. For example, under section 6103, IRS may disclose return information related to taxes imposed under the IRC—such as self-employment income tax, Social Security and Medicare tax and income tax withholding—to the Social Security Administration (SSA) as needed to carry out its responsibilities under the Social Security Act. However, according to FinCEN officials, FinCEN, law enforcement, and regulators often cannot access information submitted on Forms 8938. While section 6103 provides other exceptions to disclosure prohibitions—such as allowing IRS to share return information with law enforcement agencies for investigation and prosecution of nontax criminal laws—such information is generally only accessible pursuant to a court order. As noted above, information reported on the FBAR can be used by law enforcement agencies to aid regulatory and criminal investigations. This includes IRS, which has been delegated responsibility from FinCEN to enforce compliance with FBAR reporting requirements. IRS has used FBAR information in addressing taxpayer noncompliance with reporting and paying taxes on foreign assets and income. For example, taxpayers accepted into one of IRS’s offshore voluntary disclosure programs must have filed amended or late FBARs as part of their program applications. Investigators from IRS’s Criminal Investigation division generally reviewed applications to determine if the taxpayer has made a complete and truthful disclosure. IRS examiners can also use information from case files of program participants—such as information disclosed on FBARs— to identify new groups of taxpayers suspected of hiding income offshore. IRS can then choose to continue offering offshore programs and encourage these newly identified groups of taxpayers, as well as all taxpayers with unreported offshore accounts, to disclose their accounts voluntarily. In addition to eliminating overlapping reporting requirements, harmonizing statutes governing foreign financial asset reporting and use of information collected on such assets to make such statutes fully consistent could yield additional benefits to both IRS and the law enforcement community. Specifically, and as shown in appendix IV, there are specified foreign financial assets reported on Form 8938—such as foreign hedge funds and foreign private equity funds—that are not required to be reported on an FBAR. In contrast, there are other specified foreign financial assets reported on an FBAR—such as indirect interests in foreign financial assets through an entity—that are not required to be reported on Form 8938. Without congressional action to address overlap in foreign financial asset reporting requirements, IRS and FinCEN will neither be able to coordinate efforts to collect and use foreign financial asset information, nor reduce unnecessary burdens faced by U.S. persons in reporting duplicative foreign financial asset information. FFIs Face Overlapping Foreign Account Reporting Systems, but Alignment Would Entail Significant Changes in Law Two reporting systems for sharing foreign account information from foreign financial institutions are in operation globally—FATCA and the Common Reporting Standard (CRS). According to officials from banking associations and a consulting firm, FFIs in the countries where we examined FATCA implementation encountered challenges implementing and now maintaining two overlapping reporting systems for collecting and transmitting account information to other countries for a seemingly similar purpose, and collecting sufficient information from customers to ensure they meet the requirements of both systems. As noted above, we previously identified overlap as occurring when multiple agencies or programs have similar goals, engage in similar activities or strategies to achieve them, or target similar beneficiaries. According to an IRS official, collecting account information under FATCA ushered in an era of greater transparency; as noted above, FATCA’s passage sought to reduce tax evasion by creating greater transparency and accountability with respect to offshore accounts and other assets held by U.S. taxpayers. When FATCA was first introduced, there was no international platform to share account information between countries. The United States and other countries worked together to reach an agreement on the electronic formatting that would be used to share the information. Other countries tax authorities’ became more interested in understanding the financial assets held abroad by their residents through an exchange of account information among themselves. In response, the Organisation for Economic Co-operation and Development (OECD) established the CRS reporting system for automatic exchange of information among member countries. According to the OECD, CRS was developed with a view to maximize efficiency and reduce cost for financial institutions. Thus, CRS drew extensively on the intergovernmental approach used to implement FATCA reporting requirements for FFIs. Countries participating in CRS exchange account information with each other using OECD’s Common Transmission System, which was modeled on FATCA’s International Data Exchange System. Figure 2 depicts the flow of account information between countries under FATCA and CRS. CRS reporting requirements are in many ways similar to FATCA, including required reporting of the account holders’ name and address, taxpayer identification number, account number, account balance, and income and sales proceeds. However, the requirements differ in significant ways. The biggest differences in requirements are driven by the nature of the U.S. tax system. The United States, like many countries, generally taxes citizens and resident aliens on their worldwide income regardless of where that income is earned. However, the United States differs from other countries because it generally subjects U.S. citizens who reside abroad to U.S. taxation in the same manner as U.S. residents. In contrast to U.S. policy, most other countries do not tax their citizens if they reside in a country other than their country of citizenship. Further, IGAs implementing FATCA require FFIs to report the foreign-held accounts of U.S. citizens and residents—including resident aliens—while CRS requires financial institutions in jurisdictions participating in CRS to report on almost all accounts held by nonresidents of the reporting country. Appendix V provides more detailed information on differences in reporting requirements, due diligence requirements, and definitions under FATCA and CRS. These differences in tax systems drive variations in due diligence procedures between FATCA and CRS. For example, FATCA aims to identify whether an account holder at a foreign institution is a U.S. person based on citizenship and tax residency information. In contrast, CRS aims to identify the tax residency of all account holders of a financial institution, and does not consider citizenship. Due to the multilateral nature of CRS, if an account holder is determined on the basis of the due diligence procedures to have residency in two or more countries, information would be exchanged with all jurisdictions in which the account holder is determined a resident for tax purposes. Under CRS rules, information about foreign accounts held by a U.S. citizen with a tax residence abroad would not be reported to IRS, but rather to the jurisdiction in which they were a resident for tax purposes. Because the United States taxes the worldwide income of U.S. citizens, CRS rules would need to require identification of account holders’ citizenship in member countries where they are residents if FATCA were to be aligned with CRS. Table 5 shows a comparison of individuals reported to IRS under FATCA and hypothetically under CRS. Treasury and IRS, as part of its 2017-2018 Priority Guidance Plan, are considering modifying certain elements of the existing FATCA regulations. For instance, Treasury and IRS are considering coordinating certain documentation requirements for participating FFIs with the requirements under IGAs. In December 2018, Treasury and IRS also proposed regulations intended, in part, to reduce the burdens of FATCA. The proposed regulations included a clarification of the definition of an investment entity that is similar to the guidance published by OECD interpreting the definition of a “managed by” investment entity under CRS. If the United States wanted to adopt CRS, some of the key differences between FATCA and CRS—as outlined above and in appendix V—could be aligned through regulation while others would require legislation. According to Treasury officials, to align FATCA and CRS, Congress would need to revise statutes to: provide for the collection of information for accounts that residents of partner jurisdictions maintain at U.S. financial institutions; require certain U.S. financial institutions to report the account balance (including, in the case of a cash value insurance contract or annuity contract, the cash value or surrender value) for all financial accounts maintained at a U.S. office and held by foreign residents; expand the current reporting required with respect to U.S. source income paid to accounts held by foreign residents to include similar non-U.S. source payments; require financial institutions to report the gross proceeds from the sale or redemption of property held in, or with respect to, a financial account; and require financial institutions to report information with respect to financial accounts held by certain passive entities with substantial foreign owners. While better aligning FATCA and CRS to some extent is possible, anything short of the United States fully adopting CRS would not fully eliminate the burdens of overlapping requirements that FFIs must currently meet under the two different systems. While having the United States adopt the CRS reporting system in lieu of FATCA could benefit FFIs that may otherwise have to operate two overlapping reporting systems, it would result in no additional benefit to IRS in terms of obtaining information on U.S. accounts. Additionally, it could generate additional costs and reporting burdens to U.S. financial institutions that would need to implement systems to meet CRS requirements. The extent of these costs is unknown. Further, adoption of CRS would create the circumstance where foreign accounts held by U.S. citizens with a tax residence in partner jurisdiction—including U.S. citizens who have a U.S. tax obligation—would not be reported to IRS. Agencies Coordinated Efforts to Address Challenges U.S. Persons Living Abroad Encountered from FATCA Implementation, but Opportunities Exist to Enhance Collaboration Some U.S. Persons Living Abroad Encountered Reduced Access to Financial Services Due in Part to Costs and Risks FFIs Faced from Implementing FATCA Tax practitioners and others we interviewed said that U.S. persons living abroad—whether or not they are required to complete a Form 8938—risk being denied access to foreign financial services. U.S. persons and tax practitioners located in four of the five countries where we conducted focus groups and interviews reported that some U.S. persons and U.S.- owned businesses encountered difficulties opening bank accounts with FFIs after FATCA was enacted, with some FFIs closing U.S. persons’ existing accounts or denying them opportunities to open new accounts. One focus group participant, for example, said that the financial institution closed down all accounts including business checking, savings, and money market accounts after FATCA was implemented, requiring this individual to find a local resident who could co-sign on a new account. Costs FFIs would incur from implementing FATCA were cited as a significant factor in increasing barriers faced by U.S. persons in accessing foreign financial services. Officials from one organization representing tax attorneys said that as a result of costs associated with FATCA implementation, FFIs have found it less burdensome to close accounts of U.S. persons or require the accounts to be moved to a Securities and Exchange Commission registered affiliate than comply with FATCA. Tax practitioners and an official from a bankers association added that because FFIs may gain only small margins of profit from U.S. persons, FFIs may believe it is too troublesome to do business with them. Additionally, officials from a foreign government agency told us that because FATCA is expensive for FFIs to continue implementing, banks in their country might charge U.S. persons seeking access to financial services additional fees to account for FATCA implementation costs. Tax practitioners, consultants working with FFIs to implement FATCA reporting requirements, and the National Taxpayer Advocate told us that FFIs with smaller asset sizes such as smaller trust companies were more prone to decline business with U.S persons. Officials from an advocacy group representing U.S. persons living abroad told the National Taxpayer Advocate that some smaller banks declined U.S. persons as customers as a business decision, believing it would cost more for them to comply with FATCA reporting requirements than maintain U.S. expatriates’ accounts. Banking associations we interviewed said that decisions made by FFIs on whether to accept U.S. persons as customers also depends on the overall risks and benefits of taking on individual U.S. persons, shaped in part from risks in not meeting FATCA reporting requirements. Representatives of a banking association and an advocacy group told us that some FFIs decided to avoid doing business with U.S. persons after they became concerned about potential penalties for failure to comply—either willfully or in error—with FATCA reporting requirements. One banking association added that such errors could affect other aspects of FFIs’ relationships with the U.S. government, such as nonprosecution agreements made with the U.S. Department of Justice. Officials from one consulting firm that helped FFIs meet FATCA reporting requirements added that FFIs’ determination of risk depends on many layers, such as the value of clients’ assets or the country in which clients reside or possess citizenship. After FATCA’s implementation, according to officials from the consulting firm, FFIs decided to turn away U.S. persons in some cases because the benefits of doing business with U.S. persons were less than the potential risks. For example, if a U.S. person only maintained a payroll account, the FFI may determine it would not make enough money to account for risks in incorrectly identifying the status of the customer as a U.S. or non-U.S. person. However, focus group participants from two countries said that FFIs may agree to accept U.S persons as customers if they have higher account balances that offset risks from FATCA reporting requirements. One focus group participant, for instance, said banks in his country will do business with a U.S. person if he or she has more than $500,000 in assets. Additionally, U.S. persons and tax practitioners we interviewed said that other factors such as language barriers and U.S. regulations designed to prevent money laundering may also inhibit U.S. persons’ access to brokerage accounts while overseas. Form 8938 Reporting Requirements for Individuals with Signature Authority on and Financial Interest in Accounts May Have Contributed to Employment and Promotion Denials Overseas Focus group participants and others we interviewed said that Form 8938 reporting requirements contributed to denials of employment and promotion opportunities for U.S. persons living abroad. Treasury officials noted that requirements imposed by FATCA do not directly hinder U.S. persons from gaining employment or promotion opportunities overseas. However, focus group participants, a consulting firm, and a foreign government agency noted that foreign-owned companies and nonprofit organizations such as churches did not want to hire or promote U.S. persons because they wanted to avoid exposing information to the U.S. government on their organizations’ accounts and client trust accounts where the U.S. person would have signature authority. As noted above, a U.S. person is generally required to report on the Form 8938 foreign financial accounts for which the person has signature authority if he or she has a financial interest in the account. Focus group participants and others noted that such requirements have adversely affected the ability of U.S. persons to serve on a corporate board or in a nonprofit organization, or maintain business relationships. Treasury and Department of Commerce officials stationed in one country included in our review added that FATCA implementation has played a role in dissuading foreign-owned corporations in some Asian countries from considering U.S. persons for corporate leadership positions such as directorships. This is in part because FATCA has triggered additional paperwork burden and operating costs for onboarding U.S. employees since they have had to help them meet Form 8938 reporting requirements. Two advocacy groups representing U.S. persons living abroad added that it is also harder for U.S.-based companies to justify relocating U.S. persons overseas and paying for such relocations since they also have had to help their U.S. employees meet Form 8938 reporting requirements in addition to meeting other tax filing requirements. U.S. Persons Living Abroad Encounter Challenges Obtaining Social Security Numbers Necessary to Meet U.S. Tax Obligations and Obtain Financial Services U.S. embassy documents indicate there was increased demand for Social Security Numbers (SSN) since FATCA’s passage in 2010, driven in part by U.S. citizens applying for an SSN to gain access to foreign financial services or resolve outstanding U.S. tax obligations before completing renunciation. However, officials from two organizations representing Americans living abroad cited significant challenges faced by some U.S. persons living abroad in obtaining SSNs required to meet their U.S. tax obligations or obtain financial services. U.S. persons living abroad might not possess an SSN because their parents did not obtain one for them as a minor. Often, this may have been due to the parents leaving the United States when the child was young. State officials also said that U.S. citizens applying for U.S. passports while overseas frequently forget their SSNs or do not know if their parents ever applied for an SSN on their behalf. Officials from organizations representing U.S. persons living abroad added that without an SSN, these persons are unable to claim refunds or other tax benefits when filing their tax returns, or participate in IRS programs to voluntarily disclose previously unreported tax liabilities and assets. Additionally, some might be unable to gain or maintain access to financial accounts or other assets in their countries of residence without an SSN. According to these officials and tax practitioners we interviewed, U.S. persons living abroad face greater challenges in obtaining SSNs than those living in the United States. For instance, they faced difficulties obtaining documentation from the United States that the Social Security Administration (SSA) requires with SSN applications; traveling to Social Security offices and U.S. embassies or consulates to certify documents or submit applications in person; and receiving valid SSNs from SSA in a timely manner to file tax returns or participate in offshore disclosure programs. SSA officials also identified several challenges U.S. persons experience when applying for an SSN from abroad. For instance, SSA officials said that efforts to authenticate documents submitted with SSN applications can cause delays for U.S. persons living abroad in obtaining an SSN. Additionally, SSN applicants living abroad face significantly longer wait times than applicants living in the United States once their applications are processed. According to SSA officials, after an application is processed, it can take 3 to 6 months–-depending on the country’s mail service–-for an individual to receive a Social Security Card. This is significantly longer than the 2-week period it takes SSN applicants to receive a card after mailing in their applications from within the United States. FATCA Implementation Contributed to Increased Renunciations of U.S. Citizenship, but the Extent of the Effect is Unclear According to Department of State (State) data, the annual number of approvals of requests for renunciations of U.S. citizenships increased nearly 178 percent during a 6-year period, from 1,601 in 2011—the year after FATCA was enacted—to 4,449 in 2016, the most recent year to which full data on renunciations were available. According to U.S. embassy documents and information provided by focus group participants and interviewees across all the countries we examined, FATCA was the reason or a contributing factor in some of these decisions and the resulting increase in total renunciations. Specific effects of FATCA implementation contributing to decisions to renounce U.S. citizenship included reduced access to foreign financial services and employment or promotion opportunities in a foreign-owned company—as identified above from our document reviews, focus groups, and interviews—and burdens in meeting FATCA reporting requirements. However, the extent to which FATCA implementation contributed to increased renunciations is unclear. State officials said that data are unavailable to determine the extent to which these renunciation decisions were the direct result of FATCA because State has no legal obligation to collect information on the motivation behind renunciation of citizenship. Treasury, State, and SSA Initially Collaborated to Remedy FATCA-Related Issues for U.S. Persons Abroad, but Problems Persist without Cross- Agency Efforts to Address Them In response to concerns about the availability of foreign financial services, Treasury implemented regulations that allow certain low-risk local FFIs to be deemed compliant with FATCA, but only if the FFIs do not implement policies or practices that discriminate against opening or maintaining accounts for specified U.S. persons. Treasury and State also previously established joint strategies to address these challenges. For instance, Treasury and State developed guidance on FATCA that was posted on embassy websites to educate U.S. persons and others. Additionally, Treasury and State officials conducted outreach events and workshops through U.S. embassies and American chambers of commerce worldwide to provide information on FATCA and other tax filing requirements, According to State officials, the U.S. embassies in at least two countries—Switzerland and France—also worked with foreign officials and/or FFIs to increase access to financial services for U.S. citizens residing in those countries. For instance, Treasury and State officials reached agreements with FFIs in Switzerland to provide a wider range of financial services to U.S. persons. Similarly, in 2017, SSA and State implemented an interagency agreement to streamline processes for providing SSNs to U.S. persons living abroad after FATCA’s implementation in 2010. SSA officials said they are also in discussions with State on improving SSA’s website to include more transparent, specific information for SSN overseas applicants about SSA documentation requirements. Tax practitioners, advocacy groups, and Treasury officials we interviewed said FFIs have become more willing to accept U.S. persons as customers compared to when FATCA was enacted in 2010. However, U.S. persons living abroad continue to face issues gaining access to foreign financial services. For example, in a September 2018 letter sent by the Chair of the Finance Committee of the Netherlands House of Representatives to a member of Congress, U.S. citizens born outside the United States and who have never lived, studied, or worked in the United States are effectively being denied access to financial services in the Netherlands. Focus group participants added that some banks will reject U.S. clients or charge heavy fees for them to open an account. Agencies have ongoing efforts to address FATCA-related issues, as listed below, but some are ad hoc, fragmented, or otherwise not part of a broader effort between Treasury and other agencies such as State or SSA to use ongoing collaborative mechanisms to monitor and share information on such issues, and jointly develop and implement steps to address them: Treasury officials said they are participating in discussions with FFIs to address residual issues with access to foreign financial services. However, they said they have not involved other agencies in these discussions. IRS officials, in response to concerns from the French government, said they are developing a program to help streamline foreign asset- related tax compliance requirements for a small group of U.S. born citizens that have been French residents most of their lives without an SSN, and—according to State officials—did not wish to take the necessary steps to renounce their citizenship. However, no effort has been made to address these issues more broadly. State encouraged U.S. citizens to alert the nearest U.S. embassy of any practices they encounter with regard to the provision of financial services. State documents noted that some Americans have been turned away by banks or required to meet a higher deposit threshold in part because of FATCA reporting requirements. State documentation also noted that there have been cases of U.S. citizens with existing bank accounts who have been asked to close them. However, State documentation we reviewed does not highlight collaborative efforts currently underway with Treasury or other agencies to address banking access issues U.S. persons living abroad are presently encountering worldwide. As described above, SSA and State streamlined processes and policies for U.S. persons abroad seeking to obtain SSNs. However, SSA officials said they have not been involved in any ongoing efforts involving Treasury to identify systemic issues and related solutions involving SSNs for the purposes of tax compliance and citizenship renunciations. Treasury officials said they spoke with SSA officials about problems U.S. persons living abroad face in obtaining SSNs, but SSA believed that cycle times for processing SSN applications submitted by U.S. persons living abroad were not significantly greater than for applications submitted by U.S. persons living in the United States, although mailing times could vary significantly and take up to 3 to 6 months. We have previously identified key practices to enhance and sustain interagency collaboration, including defining and articulating a common outcome, establishing mutually reinforcing or joint strategies, and developing mechanisms to monitor, evaluate, and report on results. One goal in IRS’s strategic plan is to collaborate with external partners proactively to improve tax administration, while objectives in SSA’s strategic plan include improving service delivery and expanding service delivery options. Additionally, according to State’s Bureau of Consular Affairs website, one of State’s key priorities is to protect the interests of U.S. citizens overseas, such as through ensuring responsive and efficient provision of consular services overseas. As noted above, there are a host of ongoing issues and challenges for U.S. persons living abroad from implementation of FATCA, such as loss of access to foreign financial services, denial of employment and promotion opportunities overseas, and difficulty obtaining SSNs from abroad. However, Treasury currently lacks a collaborative mechanism to coordinate efforts with other agencies to address these issues, and Treasury officials said they do not plan to establish them. Without effective collaborative mechanisms to monitor and share information and implement cross-agency solutions, future efforts to address such issues will continue to be fragmented and less effective than they otherwise could be. Conclusions In enacting FATCA, Congress sought to reduce tax evasion by creating greater transparency and accountability over offshore assets held by U.S. taxpayers. Because of FATCA, IRS receives information on foreign financial assets from hundreds of thousands of filers annually. IRS could use this information to help ensure taxpayers holding offshore assets report and pay taxes owed on income generated from such assets. However, to take full advantage of the information, IRS must address key challenges. Specifically, Taxpayer Identification Numbers (TIN) reported by FFIs are often inaccurate or incomplete, which makes it difficult for IRS to match information reported by FFIs to individual taxpayers. As such, IRS must develop a plan to mitigate the risks that these data issues pose to agency efforts to identify and combat taxpayer noncompliance. Lack of consistent, complete, and readily available Form 8938 and related parent individual tax return data also affects IRS’s compliance activities, making it more difficult for IRS business units to extract and analyze FATCA data to improve tax compliance efforts and reduce tax revenue loss from income generated from offshore assets. At the same time, IRS has stopped following its FATCA Compliance Roadmap it developed in 2016 because, according to IRS officials, IRS moved away from updating broad strategy documents to focus on individual compliance campaigns. However, in light of the challenges IRS continues to face in fully integrating FATCA information into its compliance programs, it will not maximize use of such information and effectively leverage individual compliance campaigns unless it employs a comprehensive plan that enables IRS to better leverage such campaigns to improve taxpayer compliance. Our analysis of available data indicates that many of the Forms 8938 filed in tax year 2016 may have been filed unnecessarily. Factors that are contributing to this unnecessary reporting are unclear. While IRS has provided instructions and guidance on its website for completing Form 8938, focus group participants and tax practitioners reported confusion on whether and how to report investments in foreign accounts. Taking steps to identify and address factors contributing to unnecessary Form 8938 reporting would help reduce taxpayer burden and reduce processing costs for IRS. Reporting requirements for foreign financial assets under FATCA overlap with reporting requirements under FBAR. These overlapping requirements—implemented under two different statutes—have resulted in most taxpayers filing Forms 8938 also filing FBARs with FinCEN. Duplicative filings on foreign financial assets cause confusion, frustration, and compliance burdens for taxpayers. Duplicative filings also increased costs to the government to process and store the same or similar information. Modifying the statutes governing the requirements can fully address the issues outlined above, and can allow for the use of FATCA information for prevention and detection of financial crimes. This is similar to other statutory allowances for IRS to disclose return information for other purposes, such as for determining Social Security income tax withholding. Lastly, FATCA has created challenges for some U.S. persons living abroad that go beyond increasing their tax compliance burdens. Some U.S. persons living abroad are still facing issues accessing financial services and employment and obtaining SSNs. Treasury, State, and SSA have taken some steps to address these issues both separately and in coordination with each other. However, Treasury, as the agency ultimately responsible for effective administration of FATCA, currently lacks a collaborative mechanism with State and SSA to address ongoing issues. Establishing a formal means to collaboratively address burdens faced by Americans abroad from FATCA can help agencies develop effective solutions to mitigate such burdens. Matter for Congressional Consideration We are making the following matter for congressional consideration: Congress should consider amending the Internal Revenue Code, Bank Secrecy Act of 1970, and other statutes, as needed, to address overlap in foreign financial asset reporting requirements for the purposes of tax compliance and detection, and prevention of financial crimes, such as by aligning the types of assets to be reported and asset reporting thresholds, and ensuring appropriate access to the reported information. Recommendations for Executive Action We are making the following four recommendations to IRS: The Commissioner of Internal Revenue should develop a plan to mitigate risks with compliance activities due to the lack of accurate and complete TINs of U.S. account holders collected from FFIs. (Recommendation 1) The Commissioner of Internal Revenue should ensure that appropriate business units conducting compliance enforcement and research have access to consistent and complete data collected from individuals’ electronic and paper filings of Form 8938 and elements of parent individual tax returns. As part of this effort, the Commissioner should ensure that IRS provides clear guidance to the business units for accessing such data in IRS’s Compliance Data Warehouse. (Recommendation 2) The Commissioner of Internal Revenue should employ a comprehensive plan for managing efforts to leverage FATCA data in agency compliance efforts. The plan should document and track activities over time to ensure individuals and FFIs comply with FATCA reporting assess and mitigate data quality risks from FFIs; improve the quality, management, and accessibility of FATCA data for compliance, research, and other purposes; and establish, monitor, and evaluate compliance efforts involving FATCA data intended to improve voluntary compliance and address noncompliance with FATCA reporting requirements. (Recommendation 3) The Commissioner of Internal Revenue should assess factors contributing to unnecessary Form 8938 reporting and take steps, as appropriate, to address the issue. Depending on the results of the assessment, potential options may include: identifying and implementing steps to further clarify IRS Form 8938 instructions and related guidance on IRS’s website on determining what foreign financial assets to report, and how to calculate and report asset values subject to reporting thresholds; and conducting additional outreach to educate taxpayers on required reporting thresholds, including notifying taxpayers that may have unnecessarily filed an IRS Form 8938 to reduce such filings. (Recommendation 4) We are also making the following recommendation to Treasury: The Secretary of the Treasury should lead efforts, in coordination with the Secretary of State and Commissioner of Social Security, to establish a formal means to collaboratively address ongoing issues— including issues accessing financial services and employment and obtaining SSNs—that U.S. persons living abroad encounter from implementation of FATCA reporting requirements. (Recommendation 5) We are also making the following recommendation to State: The Secretary of State, in coordination with the Secretary of the Treasury and Commissioner of Social Security, should establish a formal means to collaboratively address ongoing issues—including issues accessing financial services and employment and obtaining SSNs—that U.S. persons living abroad encounter from implementation of FATCA reporting requirements. (Recommendation 6) We are also making the following recommendation to SSA: The Commissioner of Social Security, in coordination with the Secretaries of State and Treasury, should establish a formal means to collaboratively address ongoing issues—including issues accessing financial services and employment and obtaining SSNs—that U.S. persons living abroad encounter from implementation of FATCA reporting requirements. (Recommendation 7) Agency Comments and our Evaluation We provided a draft of this report to the Secretaries of State and the Treasury, Commissioner of Internal Revenue, and Acting Commissioner of Social Security. IRS provided written comments that are summarized below and reprinted in appendix VI. IRS did not state whether it agreed or disagreed with our four recommendations but otherwise provided responses. Regarding our recommendation to develop a plan to mitigate risks with compliance activities due to the lack of accurate and complete TINs of U.S. account holders collected from FFIs (recommendation 1), IRS reiterated that it provided a transition period, through the end of 2019, for compliance with the TIN requirements for FFIs in countries with Model 1 IGAs with the United States. IRS also said that it continued to make progress on improving FATCA filing compliance, citing efforts such as initiating a campaign addressing FFIs that do not meet their compliance responsibilities. While these efforts may help IRS obtain more accurate and complete information from financial accounts, IRS did not specify how it will mitigate the ongoing hurdles it faces in matching accounts reported by FFIs without valid TINs to accounts reported by individual tax filers and ensure compliance. Regarding our recommendation that appropriate business units have access to consistent and complete data collected from Forms 8938 and tax returns filed by individuals (recommendation 2), IRS reiterated that RAAS has been working to obtain read-only access to the IPM database but that limited budgetary resources are delaying implementation. Enabling access to consistent and complete Form 8938 and tax return data would help IRS better target compliance initiatives and leverage limited available enforcement resources. While IRS continues to work on enabling access to IPM, it could still provide clear guidance to its business units for accessing Form 8938 and tax return data in IRS’s Compliance Data Warehouse, as we recommended. Regarding our recommendation to employ a comprehensive plan for managing efforts to leverage FATCA data in agency compliance efforts (recommendation 3), IRS said the resources that would be required to develop a comprehensive plan would be better spent on enforcement activities. While implementing enforcement activities could increase compliance with FATCA reporting requirements, it risks not maximizing the value of such efforts without a comprehensive plan to manage and address the myriad of challenges discussed in this report. Further, it is our belief that IRS’s failure to execute the FATCA roadmap is not justification for abandoning a strategic approach going forward. Regarding our recommendation to assess factors contributing to unnecessary Form 8938 reporting and take appropriate steps to address the issue (recommendation 4), IRS said it will continue to observe filings of Form 8938 and, to the extent that there are unnecessary filings, assess options to inform account holders to reduce reporting and filing burdens followed by appropriate steps to implement any selected options. Our analysis of available data indicates that many Forms 8938 may have been filed unnecessarily. Implementing our recommendation reduces the risk that taxpayers file—and IRS processes—forms unnecessarily. Treasury provided written comments but did not state whether it agreed or disagreed with our recommendation that it lead efforts, in coordination with State and SSA, to establish a formal means to collaboratively address ongoing issues that U.S. persons living abroad encounter from implementation of FATCA reporting requirements (recommendation 5). Treasury said it will work collaboratively with State and SSA to answer questions that Americans abroad have regarding their tax obligations and, where appropriate, to direct U.S. citizens to resources that will help them understand the procedures applied by SSA to apply for an SSN. However, Treasury said it is not the appropriate agency to lead coordination efforts involving foreign employment issues and issues regarding access to foreign financial services and obtaining SSNs. As we noted above, Treasury is ultimately responsible for effective administration of FATCA. As such, it is in a better position than State or SSA to adjust regulations and guidance implementing FATCA to address burdens FFIs and foreign employers face from FATCA implementation while ensuring tax compliance. Additionally, Treasury has an interest in helping U.S. persons receive valid SSNs from SSA in a timely manner to meet their tax obligations. Treasury’s written response is reprinted in appendix VII. State and SSA also provided written comments in which they concurred with our recommendations to establish a formal means to address collaboratively together with Treasury ongoing issues that U.S. persons living abroad encounter with FATCA (recommendations 6 and 7). State and SSA’s written comments are reprinted in appendices VIII and IX, respectively. Treasury, State, and SSA provided technical comments, which we incorporated as appropriate. We are sending copies of this report to the appropriate congressional committees, the Secretaries of State and the Treasury, Commissioner of Internal Revenue, Acting Commissioner of Social Security, and other interested parties. In addition, the report will be available at no charge on the GAO website at http://www.gao.gov. If you or your staff have any questions about this report, please contact me at (202) 512-9110 or mctiguej@gao.gov. Contact points for our offices of Congressional Relations and Public Affairs are on the last page of this report. GAO staff who contributed to this report are listed in appendix X. Appendix I: Objectives, Scope, and Methodology The objectives of this report are to (1) assess the Internal Revenue Service’s (IRS) efforts to use information collected under the Foreign Account Tax Compliance Act (FATCA) to improve taxpayer compliance; (2) examine available foreign financial asset reports submitted by U.S. persons, including submissions that were below required filing thresholds; (3) examine the extent to which the Department of the Treasury (Treasury) administers overlapping reporting requirements on foreign financial assets; (4) describe similarities and differences between FATCA and Common Reporting Standard (CRS) reporting requirements; and (5) examine the effects of FATCA implementation that are unique to U.S. persons living abroad. For our first objective, we reviewed Treasury Inspector General for Tax Administration reports and collected information from Treasury and IRS to summarize efforts to collect complete and valid Taxpayer Identification Numbers (TIN) from foreign financial institutions (FFI). We identified criteria from our prior work identifying key practices for risk management. The key practices are derived from the Software Engineering Institute’s Capability Maturity Model® Integration for Development and Office of Management and Budget guidance. We applied these criteria to assess steps IRS has taken to manage risks in not receiving complete and valid TIN information from FFIs. We also applied criteria from our prior work on use of documented frameworks to IRS documentation on FATCA compliance activities to determine the extent to which IRS implemented a comprehensive plan to maximize use of collected data to enforce compliance with FATCA. For our second objective, we identified total maximum account values reported by individual filers of Financial Crimes Enforcement Network (FinCEN) Form 114s (commonly known as the Report of Foreign Bank and Financial Accounts, or FBAR) in calendar years 2015 and 2016. See appendix III for more details on our methodology to evaluate these data. We also summarized the numbers of IRS Forms 8938, Statement of Specified Foreign Financial Assets (Form 8938) filed in tax year 2016, accounting for the data limitations described below. We also identified Forms 8938 filed in tax year 2016—the most recent year for which data were available—with available residency and asset information that reported specified foreign financial assets with aggregate values at or below end-of-year tax thresholds, which vary depending on the location of residence and filing status of such filers. For our third objective, we reviewed IRS and FinCEN documentation, and applied criteria from Fragmentation, Overlap, and Duplication: An Evaluation and Management Guide to identify the extent to which IRS and FinCEN were engaged in overlapping activities, and collecting duplicative information on foreign financial assets held by U.S. persons. We assessed the extent to which individual filers who submitted a Form 8938 in 2015 and 2016 also submitted an FBAR for the same year by determining the number and percentage of Forms 8938 with TINs that also match the TIN listed on the corresponding FBAR for the same year. For the three objectives described above, we assessed the reliability of data submitted on Forms 8938 filed by individuals for tax years 2015 and 2016, the most recent data available. These data were extracted from IRS’s Individual Return Transaction File (IRTF) and Modernized Tax Return Database (MTRDB) through IRS’s Compliance Data Warehouse (CDW). We also assessed the reliability of data from FBARs for calendar years 2015 and 2016 by (1) reviewing documentation about the data and the systems that produced them; (2) conducting electronic tests, such as identifying data with significant numbers of missing Form 8938 or FBAR records, or values of foreign financial assets reported outside an expected range; (3) tracing selections or random samples of data to source documents; and (4) interviewing IRS and FinCEN officials knowledgeable about the data. We also reviewed Form 8938 and relevant parent tax return data stored in IRS databases to determine whether IRS management is using quality information collected from Forms 8938 to achieve its objectives, as defined in our Standards for Internal Control in the Federal Government. We determined that data extracted from IRTF on characteristics of Form 8938 filers and from FBAR filings was sufficiently reliable for our purposes, subject to caveats identified in this report. However, we determined we could not obtain complete data on foreign financial assets reported on Forms 8938 filed on paper. For our fourth objective, we reviewed model international agreements and other documentation, and interviewed officials from Treasury, IRS, and the Organisation for Economic Co-operation and Development to compare and contrast FATCA and CRS reporting requirements. We also used the collected information to identify what changes, if any, the United States and other countries could implement to align FATCA and CRS reporting requirements. For our fifth objective, we collected documentation and conducted focus groups and semi-structured interviews with 21 U.S. persons living abroad that were subject to FATCA reporting requirements. We also conducted focus groups and interviews with tax practitioners, banking and CPA organizations, government agencies, advocacy groups representing Americans living abroad, and other organizations from the United States and five other countries (Canada, Japan, Singapore, Switzerland, and the United Kingdom). We selected these countries based on geography, relatively high numbers of U.S. expatriates and Form 8938 filers, tax information sharing agreements, and other tax treaties with the United States. The findings from the focus groups and interviews are not generalizable to other U.S. persons, tax practitioners or organizations, but were selected to represent the viewpoints of U.S. persons, FFIs, and host country tax authorities required to transmit information on foreign accounts and other specified foreign financial assets to IRS. We conducted a thematic analysis of the focus groups and interviews, and reviewed cables from U.S. embassies to identify the unique effects of FATCA implementation on U.S. persons living abroad. We collected documentation from and interviewed Treasury, IRS, Department of State, and Social Security Administration officials on steps to monitor and mitigate such effects. We also identified criteria from our prior work on key practices to enhance and sustain interagency collaboration and mechanisms to facilitate coordination. We applied the criteria to agencies’ collaborative efforts addressing issues U.S. persons living abroad faced from FATCA’s implementation, and identified the extent to which agencies established effective collaborative mechanisms to identify, assess, and implement cross-agency solutions to such issues. We conducted this performance audit from August 2017 to April 2019 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives. Appendix II: IRS Data Management Systems Storing Data from IRS Forms 8938 and Related Elements of Individual Tax Returns The following IRS databases store data collected from individuals’ electronic and paper filings of Forms 8938 and/or elements of individual parent tax returns—the filer’s address and filing status—used to determine specified reporting thresholds for Form 8938 filers: Individual Master File (IMF), which serves as IRS’s system for processing individual taxpayer account data. Using this system, accounts are updated, taxes are assessed, and refunds are generated as required during each tax-filing period. Individual Returns Transaction File (IRTF), which stores edited, transcribed, and error-corrected data from the Form 1040 series and related forms for the current processing year and two prior years. Modernized Tax Return Database (MTRDB), which serves as the official repository of all electronic returns processed through IRS’s Modernized e-File system. Tax return data is stored immediately after returns are processed. International Compliance Management Model (ICMM)-FATCA International Returns (ICMM-FIR), which collects, parses, and stores data from incoming form reports–such as Forms 8938 and 8966–into the FATCA Database (FDB), which serves as the repository where ICMM-FIR stores data and from which downstream applications can pull data. Integrated Production Model (IPM), which is a downstream data repository that houses IMF data, information returns, and other data. According to IRS officials, data from IPM are consolidated and made available to a variety of downstream, security certified, systems for use in conducive analysis, case selection, and report preparation. Additionally, data from these and other IRS databases are copied to IRS’s Compliance Data Warehouse (CDW) periodically, which captures data from multiple production systems and organizes the data in a way that is conductive to analysis. Table 6 highlights several problems with the consistency and completeness of Form 8938 and relevant parent tax return data stored across the listed databases. Inconsistent and incomplete data on address and filing status of Form 8938 filers: As noted above, elements of parent tax returns— specifically the filer’s country of residence and filing status—are used to determine specified reporting thresholds for Form 8938 filers. However, IRTF and MTRDB have inconsistent and incomplete data on addresses linked to Form 8938 filers, and report inconsistent numbers of Forms 8938 filed from a U.S. residence. For example, the variable identified as containing data on foreign countries of residence in IRTF shows approximately 8,100 foreign filers in tax years 2015 and 2016, whereas a similar variable in MTRDB shows approximately 89,000 foreign filers for those same years. Additionally, FDB does not contain country codes from paper filings of Form 8938. ICCM-FIR stores information from some elements from parent tax returns—such as TINs and document locator numbers. According to IRS officials, however, ICMM-FIR lacks data on country codes and filing status of Form 8938 filers. IRS officials said that ICMM-FIR was not designed or intended to store data on Form 8938 filers; rather, it was designed to be a database for use in comparing Form 8938 and 8966 data. In general, IRS officials indicated that they would like to adjust the way ICMM-FIR stores data, but that would require modifying the way the database was established. Incomplete data on assets reported on Forms 8938: MTRDB contains detailed information on specified foreign financial assets submitted on electronic filings of Form 8938 and the country code from which the Form 8938 was filed. IRS officials said it is not designed to store information submitted on paper filings of Forms 8938 and parent tax returns. IRS officials said that while IMF processes information transcribed from individual income tax returns, there is no requirement to cross-reference information from the tax return with information submitted with an accompanying Form 8938. Additionally, while IRS officials told us that IRTF is the authoritative source for filers of Form 8938, it does not store account and other asset information submitted from Forms 8938. When asked whether there is any move to store account and other asset information collected from Forms 8938 into IRTF, IRS officials said that the decision on what returns or portions of returns are transcribed are subject to resource constraints and are prioritized from year to year. Appendix III: Methodology and Detailed Information on 2015 and 2016 Individual FBAR Filings Table 7 shows that more than 900,000 individuals filed Financial Crimes Enforcement Network (FinCEN) Form 114s (commonly known as the Report of Foreign Bank and Financial Accounts, or FBAR) in calendar years 2015 and 2016, and declared total maximum values of accounts ranging from about $1.5 trillion to more than $2 trillion each year. We are providing a range of estimates because we found a large number of filings made potentially in error. In some cases, for instance, FBAR filers reported more than $100 trillion in foreign financial accounts. We assume many of these filings are likely made in error, but have only limited means to determine which filings have errors, and which filings have accurate information. Because we cannot independently verify the accuracy of all self-reported FBAR data, we decided to present a range of data with (1) a lower bound discarding all FBAR filings reporting total values of reported foreign financial accounts at or above $1 billion; and (2) an upper bound discarding all filings reporting total values of such accounts at or above $5 billion. Table 2 excludes amended and duplicated FBAR filings. This table also excludes FBAR filings that reported a financial interest in 25 or more financial accounts, but reported total maximum account values of $0 from parts II and III of the FBAR. Although we identified problems with the data, we determined they were reliable enough to provide an estimated range of asset values to report the scale of foreign financial accounts held by U.S. persons. Table 8 shows a detailed breakdown of 2015 and 2016 FBAR filings by residence and categories of total maximum account values reported on the FBARs. Appendix IV: Detailed Comparison of Individual Foreign Financial Asset Reporting Requirements Appendix IV: Detailed Comparison of Individual Foreign Financial Asset Reporting Requirements 26 U.S.C. § 6038D; 26 C.F.R. §§ 1.6038D-1 to 1.6038D-8. 26 C.F.R. § 1.6038D-2. Filers in this category include those who identify as single, married filing separately, “head of household,” or “qualifying widow(er).” Includes maximum value of specified foreign financial assets (Form 8938) or maximum value of financial accounts maintained by a financial institution physically located in a foreign country (FBAR). Under FATCA, any income, gains, losses, deductions, credits, gross proceeds, or distributions from holding or disposing of the account are or would be required to be reported, included, or otherwise reflected on a person’s income tax return. Under FBAR reporting requirements, a person has signature or other authority if he or she has the authority (alone or in conjunction with another) to control the disposition of money, funds or other assets held in a financial account by direct communication (whether in writing or otherwise) to the person with whom the financial account is maintained. The account itself is subject to reporting, but the contents of the account do not have to be separately reported.

target: Concerns over efforts by U.S. taxpayers to use offshore accounts to hide income or evade taxes contributed to the passage of FATCA in 2010, which sought to create greater transparency and accountability over offshore assets held by U.S. taxpayers. House Report 114-624 included a provision for GAO to evaluate FATCA implementation and determine the effects of FATCA on U.S. citizens living abroad. GAO—among other things—(1) assessed IRS's efforts to use FATCA-related information to improve taxpayer compliance; (2) examined the extent to which Treasury administers overlapping reporting requirements on financial assets held overseas; and (3) examined the effects of FATCA implementation unique to U.S. persons living abroad. GAO reviewed applicable documentation; analyzed tax data; and interviewed officials from IRS, other federal agencies and organizations, selected tax practitioners, and more than 20 U.S. persons living overseas. Data quality and management issues have limited the effectiveness of the Internal Revenue Service's (IRS) efforts to improve taxpayer compliance using foreign financial asset data collected under the Foreign Account Tax Compliance Act (FATCA). Specifically, IRS has had difficulties matching the information reported by foreign financial institutions (FFI) with U.S. taxpayers' tax filings due to missing or inaccurate Taxpayer Identification Numbers provided by FFIs. Further, IRS lacks access to consistent and complete data on foreign financial assets and other data reported in tax filings by U.S. persons, in part, because some IRS databases do not store foreign asset data reported from paper filings. IRS has also stopped pursuing a comprehensive plan to leverage FATCA data to improve taxpayer compliance because, according to IRS officials, IRS moved away from updating broad strategy documents to focus on individual compliance campaigns. Ensuring access to consistent and complete data collected from U.S. persons—and employing a plan to leverage such data—would help IRS better leverage such campaigns and increase taxpayer compliance. Due to overlapping statutory reporting requirements, IRS and the Financial Crimes Enforcement Network (FinCEN)—both within the Department of the Treasury (Treasury)—collect duplicative foreign financial account and other asset information from U.S. persons. Consequently, in tax years 2015 and 2016, close to 75 percent of U.S. persons who reported information on foreign accounts and other assets on their tax returns also filed a separate form with FinCEN. The overlapping requirements increase the compliance burden on U.S. persons and add complexity that can create confusion, potentially resulting in inaccurate or unnecessary reporting. Modifying the statutes governing the requirements to allow for the sharing of FATCA information for the prevention and detection of financial crimes would eliminate the need for duplicative reporting. This is similar to other statutory allowances for IRS to disclose return information for other purposes, such as for determining Social Security income tax withholding. According to documents GAO reviewed, and focus groups and interviews GAO conducted, FFIs closed some U.S. persons' existing accounts or denied them opportunities to open new accounts after FATCA was enacted due to increased costs, and risks they pose under FATCA reporting requirements. According to Department of State (State) data, annual approvals of renunciations of U.S. citizenship increased from 1,601 to 4,449—or nearly 178 percent—from 2011 through 2016, attributable in part to the difficulties cited above. Treasury previously established joint strategies with State to address challenges U.S. persons faced in accessing foreign financial services. However, it lacks a collaborative mechanism to coordinate efforts with other agencies to address ongoing challenges in accessing such services or obtaining Social Security Numbers. Implementation of a formal means to collaboratively address burdens faced by Americans abroad from FATCA can help federal agencies develop more effective solutions to mitigate such burdens by monitoring and sharing information on such issues, and jointly developing and implementing steps to address them.
